FREDERICK O. BALL, OF PLAINFIELD, NEW JERSEY.

ENGINE Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed February 29, 1908. Serial No. 418,420.

To all whom it may concern:

Be it known that I, FREDERICK O. BALL, a citizen of the United States,residing at Plainfield, in the county of Somerset and State of NewJersey, have invented new and useful Improvements in Engines, of whichthe following is a specification.

This invention relates to engines, and cone 'sists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and ointed out in the claims.

The object of the invention is to provide a simple and efficient meansfor lubricating the cross head wrist pins of vertical reciprocatingengines.

The invention is illustrated in the accompanying drawings as follows:Figure 1 shows a central vertical section through the engine. Fig. 2 asection through the cross head. A

In the exemplification of the invention shown it is adapted to avertical engine or a verticall horizontal engine. 1 marks the horizontalengine and 2 the vertical engine.

The cross head guides 3 of the vertical engine may be of any desiredconstruction. The cross head 4 operates in these guides. Pitman 5operates on the wrist pin 6. The pitman is provided with an oil opening7 on its upper end.

The cross head is provided with an oil way 8 extending across it andconnecting the surfaces of the cross head with the opening 9,.thisopening being the piston rod opening. Thepiston rod 9 does not extendentirely through the opening, and the opening is closed by cap 10 inwhich is arranged an oil Way directly over the opening 7 in the pitman.The cross head is provided with the oil ways 12 which extend upwardlyfrom the way 8 and terminate near the up er ends of the cross head. Thecross hea is out away at 12a, so as to guide any oil that may bedeposited upon the guide surfaces to the oil ways 12. The openings 1'3extend throu 'h the cross head guides, and are connecte with the oilcups 14.

Oil is supplied to the oil cups 14 and delivered from vthem through theo enings 13 to the surface of the guides, thus ubricating the guides.Oil is also taken up by the cross head and conducted through the ways 12and 8 to the opening 9 from which it passes by gravity through theopening 11 into the opening 7, so that the cross head wrist pin islubricated in this manner.

What I claim as new is: Y

1. In an engine, the combination of the vertical cross head guide havingthe oil passage 13 therein g the cross head having an oil way extendingfrom the surface to a point over the pitman; a wrist pin on the crosshead and a pitman having an oil Way in position to receive oil bygravity from the Way in the cross head.

2. In an engine, the combination of a vertical cross head guide; meansfor delivering oil to the surface of the guide; a cross head having anoil way extending from the surface thereof to a point over the pitman,said cross head being adapted to take up the oil onthe cross head guideand conduct it to said way; a Wrist pin on the cross head; and a pitmanhaving an oil way to receive oil by graviiy from Way in the cross head.

3. n an engine the combination of a vertical cross head guide; means fordelivering oil to the surface of the guide; a cross head having thetapered end, and ways 12 and 8 leading from its surface to a centralpoint in the cross head; a wrist pin in the cross head, and a pitmanoperating on the wrist pin, and having a way in position to receive oilfrom the way in the cross head.

4. In an engine, the combination of a vertical cross head guide havingpassages 13 leading to the surfaces of said guides; the cross headoperating in said guides, having tapered ends and ways 12 and 8 leadingfrom the surface to a central point thereof; a wrist pin and cross head;and a pitman on the Wrist pin, said pitman having a way adapted toreceive oil from way in the cross hea In testimony whereof I havehereunto set my hand in the presence of two subscribing witnesses.
